Since 1967, Pepe’s Mexican Restaurants has nourished hungry families with a sweeping menu of authentic Mexican fare in colorful laid-back establishments all around Chicago. Chefs pound ripe avocados into fresh, creamy guacamole daily, which can be served with chips for dipping ($6.95) or with brushes for painting emerald moustaches on sleeping uncles. The tostadas suizas arrive with open-faced tacos that reveal what other tacos keep hidden from the world, including layers of fried beans, melted cheese, ranchera sauce, and your choice of beef, chicken, or pork ($9.25 for two; $11.25 for three). Pepe’s chefs mix and match classic Mexican dishes to create an encyclopedia of combination platters accompanied by rice and beans, such as the Chiquita ($8.95), a taco and tostada suiza, or the Puebla ($10.75), a chile relleno, taco, and tamale. Build your own meal with the chicken fajitas, which come with warm corn or flour tortillas, sizzling strips of poultry, sautéed spanish onions, tomatoes, and ringing bell peppers ($13.95). Pepe’s strawberry or mango twisted margaritas fuse unique fruit flavors into the traditional cocktails ($8.95) and land on tables in a free souvenir glass that can keep ancestral drinking crests company on mantle pieces at home.
